Answer:

3) y +3=4x

Step-by-step explanation:

The y-intercept of a graph is the point where the line crosses the y-axis. This means that the x-value of the y-intercept is always 0.

To find the y-intercept of a function, we can simply set x to 0 and solve for y.

Let's do this for each of the four functions:

1) 25+5y= 5x

If we set x to 0, we get:

25+5y= 5 × 0

25+5y= 0

5y= -25


y =(-25)/(5)

y= -5

Therefore, the y-intercept of the first function is (-5,0).

2) 6y+x =18

If we set x to 0, we get:

6y+0 = 18

6y= 18


y =(18)/(3)

y= 3

Therefore, the y-intercept of the second function is (0,3).

3) y +3=4x

If we set x to 0, we get:

y +3=4×0

y +3= 0

y = -3

Therefore, the y-intercept of the third function is (0,-3).

4)
y = (18-6x)/(6)

If we set x to 0, we get:


\sf y = (18-6\cdot 0)/(6)


\sf y = (18)/(6)

y = 3

Therefore, the y-intercept of the fourth function is (0,3).

In the given figure, when x = 0, the line intersects the y-axis at (0,-3).

So, the answer is:

3) y +3=4x
